We know that

[perimeter of the rink]=2*(72.5+28.5)--------> 202 m

if 3 m----------------> cost <span>£250.00
202 m---------------> X
X=202*250/3----------> X=</span>£16833.33

the answer is
£16833.33

The sum of the measures of the angles is 180. The sum of the measures of the second and third angles is two times the measure of
grigory [225]
<h2>60,47,73</h2>

Step-by-step explanation:

Let the first angle be a degrees

Let the second angle be b degrees

Let the third angle be c degrees

It is given that sum of angles is 180 degrees.

so,a+b+c=180                      ...(i)

It is given that sum of the measures of the second and third angles is two times the measure of the first angle.

b+c=2\times a                     ...(ii)

It is given that the third angle is 26 more than the second.

c=26+b                                ...(iii)

using (ii) and (iii),

b+b+26=2a

b+13=a

using (i),(ii) and (iii),

a+b+c=a+a-13+26+b=a+a-13+26+a-13=3a

3a=180

a=60

b=a-13=60-13=47

c=26+b=26+47=73

the sum of two numbers is 35. the second number, y, is equal to 4 times the first number , x. which system of linear equations r
ANTONII [103]

The system of linear equations x + y = 35 and y = 4x represents the two numbers

<u>Solution:</u>

Given that, The sum of two numbers is 35  

The second number, y, is equal to 4 times the first number "x"

We have to find which system of linear equations represent the two numbers?  We have two conditions for two variables, so we can obtain two equations, which means a system of equations.

Now, 1st condition ⇒ sum of two numbers is 35 ⇒ x + y = 35  

And, 2nd condition ⇒ second number is 4 times the first number ⇒ y = 4x  

Hence, the equations, x + y = 35 and y = 4x represents the given numbers.
